THE CHALLENGES OF INTERNAL AUDIT FUNCTION IN THE NIGERIAN PUBLIC SECTOR

ABSTRACT

This research work deals with the challenges of internal audit function in the Nigerian public sector with reference to Kaduna state ministry of finance. Internal auditing is a process generally adopted towards ensuring and safeguarding of resources and promoting operational efficiency in organization. The objective of this study has been to evaluate the internal control system in the Nigerian public sectors, to ascertain the non- implementation of routine audit report and the lack of proper segregation and assignment of duties. In recent times, a combination of forces has led to a quiet revolution in the profession. Government moving towards democracy must demonstrate accountability in the use of public money and efficiency in the delivery of service. In many cases internal control system are weak, staffs are poorly paid making them unmotivated, coupled with non-implementation of routine audit report by appropriate authorities. The Responses from staffs were analyzed using relevant statistical tools from which three hypothesis were formulated and tested using Z-test statistics, while questionnaire were analyzed in tabular form using simple percentage. It was discovered that the internal audit is facing a lot of challenges which includes inadequate staffing, lack of independence, lack of facilities to carry out audit function and also poor funding. As a result of some of these challenges the effectiveness of the internal audit in the Nigerian public sectors, has been hindered as well as the organizational change it can bring to its environment. I recommend that for internal audit to be effective, it must be a completely independent group, adequately funded and equipped with qualified internal auditors as well as sufficient opportunities for internal auditors to become qualified.

1.1 BACKGROUND OF THE STUDY
Internal audit had been defined “as an independent appraisal function established within an organization to examine and evaluate its activities as a service to the organization”. Internal auditing is a process generally adopted towards ensuring and safeguarding of resources and promoting operational efficiency in organizations. The responsibilities for effective internal auditing normally rest on with the internal auditors who in turn rely a great deal on the soundness and effectiveness of internal control system.
The business world is developing so in the complex nature of the organizations. This complexity of modern organizations and hence the management has led to the much broader role at the internal audit. The role of internal audit is fast moving from mere checking of documents and physical duties to analyzing the ability of organization to react to changing circumstances.
Auditing for the public sector is aimed at prevention of mistakes, shortcomings and misdeeds in the public administration. The internal audit has become a good control measures that can foretell all the incidence of fraud and misappropriation of fund in government ministries if properly put in place.

1.2 STATEMENT OF THE PROBLEM

Many business organizations are rapidly assuming complexity resulting to remarkable reliance to internal audit and management as a wider range area of control.
In spite of the existence of internal audit departments in organizations, it is often argued that the rate of fraud and misdeeds is still on the increase, particularly in the public sector. Some people argues that the internal auditors are creating more problems than they are solving, others see it as tools for witch-hunting and therefore sees them as unnecessary evil.
The internal control system in Nigeria public sector may be insufficient based on some predicaments.
 Lack of proper segregation and proper assignment of duties as well as shortage of qualified staff to carry out internal audit and accounting duties.
 Lack of implementation of routing audit report by appropriate authorities.
 Inadequacy of internal control system leading to improper investigation.
The above reasons greatly affect the effectiveness of internal audit in the public sector. This gives the researcher the impetus for undertaking a study on this study with a view coming up with solution of those challenges.
